Hmm looks good however there are various grades of stainless steel some magnetic some not, both contain nickel and have value. I have found some pretty large chunks of stainless in the past (generally recognizable as kitchen ware), you might be tossing something of value just because it's sticky, and your little scratch test on soft silver metal could fool you into thinking it was just lead when it could be something like silver solder.
Also even though it's not a valuable metal it should still be recycled just tossing it in the trash is really a bad idea for the environment. Just take it along with the good stuff to the recycler and donate it or let them weigh it up.
yes 2cents is about what you will get for the junk metal
